The deportation officer, identified as Jason Alistair Lowery, 34, had been under surveillance for more than month after a known smuggler who had been arrested gave authorities a tip about the officer in an effort to get lenient treatment, Department of Public Safety Officer Carrick Cook told The Associated Press.

In a criminal complaint filed late Wednesday against Lowery, who also used to be a Border Patrol agent, a Department of Homeland Security investigator wrote that he got further information about Lowery through a confidential informant on Oct. 4.

The informant, whose identity was protected, said that he or she was involved with Lowery and another man in a “rip” crew in which Lowery used his status in law enforcement to help steal marijuana from illegal immigrants, wrote Brian Gamberg-Bonilla, a special agent with the DPS’s Office of Investigations.

The informant agreed to call Lowery and arrange for him to pick up 500 pounds (226 kilograms) of pot in the desert on Tuesday, which is how authorities were able to follow him and begin to make their case, Gamberg-Bonilla wrote in the document.

DPS and federal agents tried to pull Lowery over after he picked up the marijuana with his unmarked ICE pickup truck, Cook said. Lowery then fled, leading agents on a 45-minute chase at speeds of up to 110 mph as he threw 10 of the 14 bundles of pot that he had in the truck out of the window, he said.

“He got pretty desperate,” Cook said.

The chase began in the Vekol Valley about 45 miles (72 kilometers) south of Phoenix and ended just south of Sacaton, about 20 miles as the crow flies northwest from where the chase began. It ended when Lowery’s truck rolled over and he gave himself up.

Lowery, who lives in the Phoenix suburb of Chandler, appeared in federal court in downtown Phoenix on Wednesday but did not address the court. He sat quietly awaiting the hearing and at one point looked up at the ceiling and repeatedly shook his head.

Prosecutor John Lopez argued that Lowery should be detained as his court case proceeds, saying that he poses a risk to the community and could flee the state. He also said that Lowery had a non-government-issued gun on him when he was arrested.

Federal Magistrate Michelle Burns set a hearing in the matter for Tuesday.

Mexican drug cartels have infiltrated federal law enforcement agencies along the border for years, targeting hiring initiatives with their own people or recruiting officers.

Between 2003 and early 2010, 129 U.S. customs officers and Border Patrol agents were arrested on corruption charges, according to Tom Frost, the Department of Homeland Security’s assistant inspector general for investigations. The office was not immediately able to provide an updated figured to the AP.

“This is becoming all too common, in my opinion,” said Jim Dorcy, a retired Border Patrol agent who later investigated corruption among agents for the Justice Department. “Statistically it’s pretty rare, but you have to understand that as a law enforcement agency, it should be approaching zero.”

He said any amount of corruption in a police agency, let alone dozens of cases, destroys the public’s confidence and criminals’ respect. The heart of the problem lies in recent hiring booms in ICE and the Border Patrol in which the bar was lowered to meet hiring quotas, Dorcy said.

As for the corruption cases he investigated, Dorcy said it usually came down greed.

“They just want to make more money than the job offers, and they get offered a very tempting amount of money,” he said.

In one notable case, former Customs officer Margarita Crispin was arrested in El Paso, Texas, in 2007 and sentenced to 20 years in prison after pleading guilty to conspiracy to import more than 1,000 kilograms (2,204 pounds) of marijuana. Prosecutors alleged that she accepted more than $5 million in bribes over several years in exchange for letting smugglers’ vehicles pass through her checkpoint without inspection.

In a more recent case, former Border Patrol agent Michael Angelo Atondo was found guilty of trafficking marijuana in southwestern Arizona after fellow Border Patrol agents found him in a remote area along the border near San Luis — several miles outside of his patrol zone — with 745 pounds (338 kilograms) of marijuana in his vehicle.

Prosecutors say Atondo appeared to be a mole who infiltrated the agency to smuggle drugs. The 34-year-old will be sentenced Jan. 9.

In Lowery’s case, DPS believes that he was taking the 500 pounds (226 kilograms) of marijuana that he picked up in the desert to a man working for a drug cartel whose house served as the nexus of the drug distribution.

Lowery was booked into Pinal County jail on charges of smuggling and felony flight and was turned over to ICE custody Wednesday morning. The sheriff’s office also booked the man who was to receive the marijuana, identified as 33-year-old Joshua Duane Powell of Arizona City.

At Powell’s home, police found 14 rifles and guns in the trunk of his car, seven of which had been reported stolen, according to a DPS document.

The document also said that Powell had been out on a $25,000 bond stemming from a separate investigation last month in which multiple bulletproof vests, weapons, stolen night-vision equipment, hundreds of rounds of ammunition and various drugs were found in his home.

Powell does not yet have an attorney and he has declined interview requests from the news media.

ICE spokesman Vinnie Picard said that Lowery worked as a deportation officer for the agency since August 2008 but declined to provide further information about Lowery.

Lowery worked as a deportation agent in ICE’s fugitive operations team, which goes after illegal immigrants who fail to leave the country after they’re ordered to be deported. Such officers carry weapons and have arrest powers.

Border Patrol spokesman Mario Escalante said Lowery also worked for that agency before going to ICE, but did not know for how long.
